本文实例讲述了vue实现的上拉加载更多数据/分页功能。分享给大家供大家参考，具体如下：
加载状态
<div v-if='has_log == 0'>
<load-more tip="上拉加载" :show-loading="false" background-color="#fbf9fe"></load-more>
</div>
<div v-if='has_log == 1'>
<load-more tip="正在加载" :show-loading="true"></load-more>
</div>
<div v-if='has_log == 2'>
<load-more tip="没有更多数据了" :show-loading="false" background-color="#fbf9fe"></load-more>
</div>
js
export default {
name: '',
data () {
return {
list: [],
now_item: '',
current_index: 0,
list_param: {page: 1},
no_data: false,
has_log: 0
}
},
components: {
XInput
},
created () {
this.get('/api/index/index', this.list_param).then((data) => {
this.list = data.data.data
this.list_param.page += 1
})
window.addEventListener('scroll', this.onScroll)
},
methods: {
onScroll () {
this.has_log = 1
let innerHeight = document.querySelector('#app').clientHeight
let outerHeight = document.documentElement.clientHeight
let scrollTop = document.documentElement.scrollTop
// console.log(innerHeight + ' ' + outerHeight + ' ' + scrollTop)
// console.log(outerHeight + scrollTop - 30)
// console.log(innerHeight)
if (outerHeight + scrollTop === innerHeight + 57) {
if (this.no_data === true) {
this.has_log = 2
return false
}
this.get('/api/index/index', this.list_param).then((data) => {
if (data.data.data.length > 0) {
this.list = [...this.list, ...data.data.data]
this.list_param.page = this.list_param.page + 1
this.has_log = 0
} else {
this.has_log = 2
this.no_data = true
}
})
}
}
}
}
希望本文所述对大家vue.js程序设计有所帮助。
